Responsibilities of an Ultrasonic Time of Flight Diffraction (TOFD) Level 2 certified NDT professional

An individual certified to Level 1 has demonstrated competence to carry out NDT according to written instructions and under the supervision of Level 2 or Level 3 personnel. Within the scope of the competence defined on the certificate, Level 1 personnel may be authorised by the employer to perform the following in accordance with TOFD NDT instructions:

  • set up TOFD equipment
  • perform the tests
  • record and classify the results of the tests according to written criteria
  • Report the results
  • TOFD Level 1 certified personnel shall neither be responsible for the choice of test method or technique to be used, nor for the interpretation of test results carry out and supervise all tasks at or below Level 2
Training and experience hours required for Certification

Full PCN certification is only achieved once the required experience is acquired following the completion of the required training hours and passing of the examination:

    Ultrasonic Time of Flight Diffraction

  • Level 1 – 40 training hours and 3 months experience

  • Prepare written Ultrasonic TOFD instructions
  • Carry out and supervise all tasks at or below Level 2
  • Provide guidance for personnel at or below Level 2
  • Report the results of Ultrasonic TOFD tests.
Training and experience hours required for Certification

Full PCN certification is only achieved once the required experience is acquired following the completion of the required training hours and passing of the examination:

    Ultrasonic Time of Flight Diffraction

  • Level 2 – 80 training hours and 12 months experience
ULTRASONIC TIME OF FLIGHT DIFFRACTION (TOFD) WELDS: LEVEL 3
Duration Type Technique
5 Days Both Theory and Practical TOFD
1 Day Both Theory & practical TOFD
Why attend this course?
This is a guidance course aimed at the PCN requirements for Ultrasonic TOFD Practitioner Level 3 in welds. The main objective is to make candidates fully aware of the scope of the examination and level of knowledge required (This will also enable candidates to identify their weak subject areas). Advice will be given on any further tuition required. Candidates should hold a PCN Level 2 in TOFD, a PCN Level 3 approval in Ultrasonic Testing as a minimum and have at least 2 years experience in NDT Inspection before attempting these courses.
Content
  • PCN requirements for Level 3 approval
  • Complementary NDT methods
  • Advanced product technology
  • Quality assurance, quality control and supervision
  • Specifications, procedures and techniques
  • Analysis of reports
  • Advanced ultrasonic testing theory and revision
  • Analysis of procedures
  • Procedure writing
  • Mock examinations
Responsibilities of an Ultrasonic Time of Flight Diffraction (TOFD) Level 3 certified NDT professional

An individual certified to Ultrasonic TOFD Level 3 has demonstrated competence to perform and direct Ultrasonic Testing operators for which he is certified. Ultrasonic TOFD Level 3 personnel have demonstrated:

  • The competence to evaluate and interpret results in terms of existing standards, codes, and specifications
  • Sufficient practical knowledge of applicable materials, fabrication, process, and product technology to select Ultrasonic TOFD methods, establish Ultrasonic TOFD techniques and assist in establishing acceptance criteria where non are otherwise available
  • A general familiarity with other NDT methods

Within the scope of the competence defined on the certificate, Ultrasonic TOFD Level 3 personnel may be authorised to:

  • Assume full responsibility for the test facility or examination centre and staff
  • Establish, review for editorial and technical correctness and validate Ultrasonic Testing instructions and procedures
  • Interpret codes, standards, specifications and procedures
  • Designate the particular Ultrasonic TOFD test methods, techniques and procedures to be used
  • Within the scope and limitations of any certification held, carry out all tasks at all levels
  • Provide guidance for Ultrasonic TOFD personnel at all levels
Level 3 certified personnel may be authorised to carry out, manage and supervise PCN qualification examinations on behalf of the British Institute of NDT (BINDT).
Where Level 3 duties require the individual to apply routine NDT by a method or methods within a particular product or industry sector, BINDT strongly recommends that the industry demand that this person should hold and maintain Level 2 certification in the applicable method(s) and sector(s).
The range and scope of PCN certification available at each level is defined in the relevant appendix to these general requirements.
